FILLING-RE'PLENISHING LOOM.

SPECIFICATION forming part of Letters Patent No. 697,004, dated April 8, 1902.

Application filed July 8, 1901. Serial No. 67,437. (No model.)

T [all whom, it 72u07/ concern:

Be it known that I, JONAS NORTHROP, a subject of the King of Great Britain, residing at Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Automatic Filling-Replenishing Looms, of which the following description,in connection with the accompanying drawings, is a speciication, like numerals on the drawings repre- 1o senting like parts.

This invention has for its object the production of an automatic filling-replenishing loom containing various novel features of construction, arrangement, and operation, as will x5 more fully appear hereinafter.

One of the novel features of my invention consists in effecting the actuation of the lling-replenishing mechanism by or through the proper boxing of the shuttle when the fillzo ing breaks, the device which becomes operative upon such occurrence being mounted on the shuttle itself.

Other novel features will be fully described in the specification and particularly pointed out in the claims.

Figure 1 is a right-hand side elevation of a portion of a loom embodying my invention, the lay and filling feeder being shown in transverse section. Fig. 2 is a top or plan 3o View of the inner end of the lay or the end at which change of lling is effected, the shuttie-box and a shuttle being shown and also a part of the means for controlling the operation of the illing-replenishing mechanism.

Fig. 3 is a top or plan view of the opposite or outer end of the lay and the shuttle-box thereon, the left-hand end of the breast-beam, and a portion of the means for suspending the action of the take-np mechanism. Fig. 4 is a 4o top or plan View of one end of the shuttle, enlarged, with the threading device and the actuator controlled by the filling while intact. Fig. 5 is a transverse sectional View of Fig. 4 on the line a; 0, Fig. 4; and Fig. 6 is a lefthand side elevation, in part, of the loom, the mechanism shown in plan Fig. 3 being herein illustrated in side elevation.

Of the filling-replenishing mechanism herein illustrated it will be necessary to state that 5o it comprises a lling-feeder 1 to contain a series of filling-carriers 2 to be removed therefrom one by one at the proper time.by the transferrer 3 and inserted in the shuttle,which is open top and bottom to receive the fresh supply of filling and permit the ejection of the spent filling-carrier in well-known manner. The transferrer is fulerumed at 4 on a stand 5, secured to the breast-beam 6 at or near one side of the loom, and a depending arm 7 on the transferrer has mounted thereon a dog 8, notched at its rear end to be at times engaged by a bunter 9 on the lay 10, such engagement acting as the lay beats up to rock the transferrer and effect a transfer of filling, all substantially as in United States Patent No. 529,940, to which reference may be had. A rock-shaft 11 is mounted in the lower end of the arm 7, and the dog S is secured to said rock-shaft, its downward movement being limited by a stop-pin 12, mounted on lthe dog and extended across the front face of the arm 7. (See Figs. 1 and 2.) The rock-shaft has an l"'shaped arm 13, the longer portion of which is parallel to the lay and extended toward it to be engaged by suitable means, to be described, to turn the dog in the direction of arrow 14, Fig. 1, and into the path of the bunter 9. At its inner end-t'. e., the one nearest the filling -replenishing mechanism-the lay is provided with a shuttle-boX-l of usual construction, except that its front wall 1G is pro vided with an aperture 17 to receive the inturned end of a cam-foot 18, secured to a dagger 19, mounted to rock on an upright stud 20.011 the lay in front of the shuttle-box. The dagger is so located relatively to the long part of the arm 13 that when the former is in dotted-line position, Fig. 2, it will engage and elevate said arm as the lay beats up, to thereby operatively position the dog 8, the free end of the dagger being bent (see Fig. 1) to constitute a species of cam-surface upon which the horizontal part of the arm 13 slides to be lifted thereby. As shown in Fig. 2, the dagger is mounted near the outer end of the shuttle-box 15, with the foot 18 normally projecting beyond the inner face of the front wall 16, a spring 21 maintaining the foot and dagger in the position shown.

I have herein provided means carried by the shuttle and rendered. operative by or through breakage or exhaustion of the fill- IOO ing to automatically eect a change of iilling on the pick,'which effects the entrance of the shuttle into the inner shuttle-box when the breakage or exhaustion of filling is detected 'on such pick of the shuttle.v l

Referring now to Figs. 2, 4, and 5, the shuttle 22 has an elongated opening 23 extended therethroughfrom top to bottom, as is common in self-threading shuttles, to contain a supply of filling 2 when transferred thereto from the feeder 1, and at one end the shuttlev is provided with a self-threading device to conduct the thread automatically to the side-delivery eye 24 of the shuttle. The threading device herein illustrated is sub- Astantially that forming the subject-matter of United States Patent No. 556,705, dated March 17, 1896, the block 25 having a threadpassage 26, Fig. 4, provided with a longitudinal entrance 27, a downturned spur 28 preventing accidental withdrawal ofthe thread from the passage26, the thread passing between the top of Vthe shuttle and the curved edge`29 of the threading-block to the delivery-eye, as in said Patent No. 556,705. I have mounted a downhold on the shuttlebody just back of the threading-block, consisting of a downturned hook 30, Fig. 5, opposite the inner end of the thread-passage 26 'and secured to or forming part of an upright post 31, bent at its upper end to engage the threading-block and at its lower end inserted in the wood of the shuttle. Between the post and the block I have mounted an actuating device comprising a body portion or actuator proper, 32, fulcrumed at 33 on a suitable stud and having a detecting-finger 34, the said device being adapted to rock in a plane transverse to the longitudinal axisof the shuttle. The actuator 32 is extended laterally through a slot 35 in the side of the shuttle, and when in vfull-line operative position, Fig. 5, the actuator projectsbeyond the side of the shuttle,

which latter is grooved longitudinally, as at 36.

When the threading of the shuttle is effected,

however, the thread between the block 25 and the lling-carrier 2 engages4 and presses down the finger 34 and lifts the actuator into dottedline position, Fig. 5, so that the actuator is above the groove 36, and the thread slips down under the hook-like downhold 30, and so long as the filling-thread is intact it will maintain the actuator ininoperative dottedline position. Breakage or exhaustion ofthe filling, however, releases the finger, the actuator drops into full-line position, Fig. 5, the body portion 32 beingthe heavier, and the projecting part in the groove 36 will be in position to engage thefoot 18, Fig. 2', and as the shuttle reaches the end of its shot and is properly boxed in the inner shuttle-box 15 the actuator willhave 'pushed the foot outward, and thereby swung the Adagger 19 into operative dotted-line position, Fig. 2, to vengage the arm 13 'as the lay beats up, as has been referredto, and filling-replenishing will be effected on that beat of the lay. The foot 18 enters the groove 3,6 at every alternate pick, but normally the actuator will be held up above it, so as to cause no eective movement of the dagger; but whenever the Iilling has broken or run out the replenishing mechanism will be operated by the proper boxing of the shuttle in the inner box.

If the shuttle is improperly boxed, the filling will not be replenished, because the final movement ofthe shuttle for a short distance after engagement of the actuator and dagger-foot 18 is absolutely necessary to operatively position the dagger, and such final movement is not present when the shuttle fails to complete fully its stroke.

The operation of the take-up mechanism need not be suspended under the foregoing conditions; but should the filling fail on the shot of the shuttle to the left or to the outer shuttle-box37, Figs. 3 and 6, then the filling cannot be replenished until the'second pick thereafter, and'unless the take-up is suspended thin places will be made in the cloth.

Of the take-up mechanism I have shown only the ratchet-wheel 38, the take-up pawlcarrier 39, having a lateral lug 40 thereon, and two let-back pawls 41 and 42, to operate successively in Well-known manner, the longer pawl 41 rocking on a fulcrum 43, supported on the loom-frame, while the shorter pawl 42 is longitudinally slotted at 44 to embrace and slide on the stud 43 when pawl 41 is raised suiiiciently to disengage it from the ratchet-wheel, the construction and operation being-substantially as in United States Patent No. 643,284, dated February 13, 1900. As in said patent, the pawl-carrier has a locking-shoulder 46 to at times engage a lateral stud on the pawl 4l, the normal position of the parts being shown in Fig. 6. The shipper 47, normallybeld in the usual notched plate 48 while the loom is running, is the only part shown of the usual stop-motion actuated by release of the shipper tostop the loom, and a knock-off lever 49 50 is fulcrumed at 51 on the breast-beam 6 to effect automatically the release of the shipper. The inner end of the lever extends behind a latch 52, pivoted at its outer end at`53 to an upturned arm 54, fulcrumed on a rod 55, suitably secured to the loom-frame and having a depending extension 56, which projects immediately infront of the let-back pawl 42 when the latter is in its normal position herein'illustrated. A spring 57 (see Fig. 3) is rigidly held at one end and at its other end is secured to the vhub of the arm 54 to maintain the extension 56 against the pawl 42, and the latch has a lateral ear 58, and at its inner end it isdownturned or l1ooked,as at 59. A second upturned arm 60 is fulcrumed v on the rod 55, and it also has a depending extension 61 to at times cooperate with the lug 40 on the pawl-carrier of the take-up mechanism, while at its upper end the arm has pivoted to it at 62 an arm 63, extended rearwardly across the breast-beam and having lse- IIO cured to or forming partof it a cam-like latch-detent 64 to coperate with the ear 58 `on the latch, and abunter 65 at its top downwardly inclined, as at 66, from front to rear and substantially in the path of movement of the latch 52. The front wall 67 of the outer shuttle-box 37 is slotted at 68 to admit an inwardly-extended trip 69, fast on a slide'- rod 70, mounted in suitable bearings 7l on the lay, and held in the position shownin Fig. 3by a spring 72, interposed between one of the bearings and a collar 73, fast on the slide-rod. The inner end of thelatterhas secured to or forming part of it a bunter 74, whichis normally at one side of the rearwardly-extended arm 63. Now if the actuator 32 is operatively positioned when the shuti tle enters the outer shuttle-box said actuator will engage the trip 69 and will move the same in the direction of-the arrow 75, Fig. 3, as the shuttle reaches the outer end of its stroke, supposing that the shuttle is properly boxed, and such movement of the slide-rod 70 will move the bunter 74 into position to engage the arm 63 as the lay beats up,'and i to thereby swing outward the upturned arm GO. Vhen this results, the depending eXtension 6l will act upon the lug 40 to move the pawl-carrier 39 to disengage the actuatingpawl from the ratchet-wheel 3S, and at the same time the projection or lug 45 will be engaged by the pawl-carrier to disengage theA pawl 4l, permitting the pawl 42 to letA back i or permit retrograde movement of the ratchetwheel in the direction ofthe arrow 76.

upon the extension 56, swinging it outward and necessarily swinging inwardly the upturned arm 54, so that the latch 52 isvmoved Y the ear 58, permittingr the latch to drop with V its hooked end in frontof the arm 50; vbut before the rearward movement of the latch just described takes place the inward movement of the arm 63 to normal position is effected, and the ear 58slides u p onto the latchdetent,so that the latch can pass over the detent-arm when it is moved rearwardly byV or through the movement of the letback pawl 42. This suspension of the operation of the take-up mechanism provides for the necessary number of picks which occur before the shuttle can be thrown to the inner shut-.

tle-box to eifect a change of` lling, so that thin places in thecloth will be prevented by thus suspending the take-up.

It sometimes happens that the shuttle will fail to thread after a fresh supply of iilling' has been inserted therein, and it is then necessaryto stop the loom, and for this purpose I have provided the latch and the latchbunter 66. i

Ask the let-back pawl 42 is thus moved tothevright or outwardly, viewing Fig. 6, it acts If theoperation justa, described has taken lplace by the entrance of the shuttle in the outer .shuttle-box 37,.suspending the action of the take-up and eifecting the movement of the latch 52 into such position that its hooked end 59 will be behind the arm 50 of theiknock- `o lever, then vsupposing that at the righthand shot the filling is inserted in the shuttle and fails to thread, Vthe actuator 32 will therefore remain operative `on the next or third shot of the shuttle to the left, and a second time successively the bunter 74 willlbe moved into position to move the arm 63 outward, andrthis second movement takes place when the downturned end or hook 59 is in the path of the bunter 65 and between the latter and the knock-off arm 50, so thatonlthe second outward movement of the arm 63 the bunter 65 will press against the hooked end of the latch 52, and it in turn will operate to swing the knock-off lever to release the shipper, so that the loom will be automatically stopped.` It will be noted that the first time the arm 63 is moved out the downturned hook 59 will drop onto or back of the bunter G5, and in order to permit the passage 0f the bunter beneath the hook as the former returns to its normal position I have inclined the upper face or top of the latch-bunter, as at 66,

so that when the arm 63 moves inward the hook will slide up the incline 66 and when released therefrom the ear 58 will drop onto the latch-detent 64.

It will be obvious that when the extension Gl is permitted to returnl to normal position, as it will by the weight of the take-up-pawl carrier acting thereupon, the said pawl-carrier will return to its normal position, so that the take-up pawl will reengage wi th the latchwheel 38,and the interrupted operation ofthe take-up will be resumed. So, too, the spring 57 acts to not only keep the extension 56 against the let-back pawl 42, but also assists in returning such pawl to its normal position,
